The GeForce 2 family comprised a number of models. The GeForce 2 GTS, GeForce 2 Ultra, GeForce 2 Pro, and GeForce 2 Ti are based upon the original architecture (NV15), varying only by chip and memory clock speeds. For the low-end segment and OEMs, the GeForce 2 MX series (NV11) was created, from which the GeForce 2 Go was derived
The Mobility Radeon 9000 was launched in early summer 2002 and was the first DirectX 8 laptop chip. It outperformed the DirectX 7-based nVidia GeForce 2 Go and was more feature-rich than the GeForce 4 Go. A Mobility Radeon 9200 later followed as well, derived from the desktop 9200.
The GeForce 256 is the original release in Nvidia's "GeForce" product line.Announced on August 31, 1999 and released on October 11, 1999, the GeForce 256 improves on its predecessor by increasing the number of fixed pixel pipelines, offloading host geometry calculations to a hardware transform and lighting (T&L) engine, and adding hardware motion compensation for MPEG-2 video.
OpenCL accelerates many scientific Software Packages against CPU up to factor 10 or 100 and more. Open CL 1.0 to 1.2 are supported for all Chips with Terascale and GCN Architecture. OpenCL 2.0 is supported with GCN 2nd Gen. (or 1.2) and higher. [18] For OpenCL 2.1 and 2.2 only Driver Updates are necessary with OpenCL 2.0 conformant Cards.
A ProSavage-DDR design also exists; the only improvement is DDR memory support - shared with the CPU/system. (The video memory can be set from 8mb to 32mb but this decreases the system's ram size. For example, if your system ram is 512MB and you set your video memory to 32MB, the operating system will read only 480MB ram.)
Further speculation included a memory controller that could support DDR SDRAM and DDR FC-RAM, DirectX 8.0 compliance, and a faster version running at 250 MHz. These specifications are somewhat reminiscent of Matrox Parhelia , in that Parhelia is a 4 pipeline DirectX 8 GPU with 4 texture units per pipeline.
One chip allows 2× AA, two chips allows 4× AA, four chips provides for 8× AA and so on. The RGSS method of anti-aliasing combines multiple samples of each frame, resulting in higher quality than the brute force ordered-grid over-sampling of ImgTech PowerVR, ATI Radeon DDR and Nvidia GeForce 2. [6]
Radeon HD 3870 X2 (codenamed R680) was released on January 28, 2008, featuring 2 RV670 cores with a maximum of 1 GiB GDDR3 SDRAM, targeting the enthusiast market and replacing the Radeon HD 2900 XT. The processor achieved a peak single-precision floating point performance of 1.06 TFLOPS, being the world's first single-PCB graphics product ...
